hgweb: add template filters, template style maps, and raw pages

Template filters:

in templates, you can now specify a chain of filters like

#desc|firstline|escape#
#desc|escape|addbreaks#
#date|age#

to specify how you'd like raw text (or whatever) to be transformed.

Template style maps:

add ;style=foo to a URL and we'll use templates/map-foo if it exists.

Raw output:

Together, these two features make it east to implement raw
downloadable files and patches. Simply link to the same page with
style=raw and present the output as unfiltered text/plain with that
template.
